stereoscopy – Is there a software solution which can replace a stereoscope?


I’m reading a relatively old paper (1976). I’m trying to figure out how to interpret the blobs on the micrograph images, and then I see this in the legend:
‘The stereoscopic pairs of micrographs, produced by tilting the specimen stage, should be viewed with a stereoscopic hand viewer.’

Now I don’t know about you, but I don’t have a stereoscopic hand viewer. I mean, I have very little idea of what that even is. However, maybe there’s software which can create a similar effect? I’m hoping that it might help me have a better understanding of the images. Help would be appreciated!
